Ian and Nina took a break from listening to music at Coachella on April 14 and stopped by the Burton Snowboards pool party and BBQ at the nearby Ace Hotel.

“There is lots of sexual heat between these two,” body language expert Dr. Lillian Glass EXCLUSIVELY tells HollywoodLife.com. “Nina is leaning her body into Ian and he has a smug smile like he is hiding something.” Hmmm…what could these two lovebirds possibly be hiding? A secret relationship?!

“They are standing chest to chest and hip to hip with no space between them and that means that they are most likely very, very close to one another,” Lillian reveals. “Nina is leaning hear head into Ian’s as well, which definitely shows intimacy.”
